INTRODUCTION
Good Manufacturing Practice (GMP) is the part of Quality Assurance that ensures that products are produced and controlled consistently and reliably. This consistency of production and control is essential. It can only come about by having clear descriptions of the way in which the work will be done.
GMP specifically addresses risks of cross-contamination and mix-up that cannot be fully controlled by testing of the final product.
These risks can best be controlled by having a properly managed system of working that takes them into account. This means that the quality checking system must be designed with these risks in mind and set out to find whether any errors have occurred.

• The terms quality assurance and quality control are often used interchangeably to refer to the actions performed for ensuring the quality of a product, service, or process.
• Both terms, however, have many interpretations because of the multiple definitions for the words "assurance" and "control."
• The definitions below, for example, point toward a specific distinction between these two terms:
Assurance = The act of giving confidence, the state of being certain, or the act of making certain.
Assurance : The act of giving confidence, the state of being certain, or the act of making certain.
Quality assurance : All the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence a product or service will fulfill requirements for quality.
Control : An evaluation to indicate needed corrective responses; the act of guiding or the state of a process in which the variability is attributable to a constant system of chance causes.
Quality control :The operational techniques and activities used to fulfill requirements for quality.

• Containers due to be sampled should be cleaned prior to sampling if necessary.
• There should be a written procedure describing the sampling operation. This should include health and safety aspects of sampling.
• The container used to store a sample should not interact with the sampled material nor allow contamination. It should also protect the sample from light, air, moisture, etc., as required by the storage directions for the material sampled.

1. Raw MaterialSampling plan for raw material should be based on defined sampling standard, for example: • the “n plan” is based on the formula n = 1+√N, where N
is the number of sampling units in the consignment;• the “p plan” is based on the formula p = 0.4 √N, where
N is the number of sampling unit; or • the “r plan” on the formula r = 1.5√N . • reduce sampling plan such as “p plan” shall be
considered only when there is established confidence on the material’s uniformity.
2. Packaging materials and Finished ProductSampling plans for packaging materials should be based on defined sampling standards, for example British Standard BS 6001-1, ISO 2859 or ANSI/ASQCZ1.4-1993.

VERIFICATION
• Applicable to equipment that cannot be calibrated (adjustment, correlation, etc)
• Verification against measurement standard with correction factor documented
• Actual reporting of result shall include the correction factor
• Temperature correction factor “- 2 0C”. Measured value: 240 CReported value = 24 0 C –2 0 C= 22 0 C

REPROCESSING (1)• Reprocessing includes both definitions of
Reprocessing and Rework • Definitions
Reprocessing: Subjecting all or part of the batch/lot of an in-process bulk, intermediate or product of a single batch or lot to the previous step of the approved manufacturing/packaging process due to failure to meet pre-determined specification.
Rework: Subjecting all or part of the batch /lot of an in-process bulk, intermediate or product of a single batch or lot to an alternate manufacturing/ packaging process due to failure to meet pre-determined specification.

CONTROL OF RETURN PRODUCTS Products that have been subjected to improper storage
conditions including extremes in temperature, humidity, smoke, fumes, pressure, age, or radiation due to natural disasters, fires, accidents, or equipment failures shall not be salvaged and returned to the marketplace.
Whenever there is a question whether products have been subjected to such conditions, salvaging operations may be conducted only if the following acceptance criteria were fulfilled: Product labeling meeting current regulatory
requirements Laboratory tests that the product meet the product
specification Visual inspection on the product and their associated
packaging were intact and comparable to standard
